Receiver Power Supply BEC (UBEC) 3A /5A /7A /15A Step-Down Regulator Module<br> Features:<br> 1. Utilizes a switching power supply structure design with a switching power supply main control chip operating at a frequency of 300 kHz, featuring overcurrent and over-temperature protection functions, and achieving a chip efficiency of up to 92%;<br> 2. Extremely compact size and lightweight design;<br> 3. Electronic components are protected by a shielding cover, and output lines are equipped with magnetic rings, significantly reducing electromagnetic interference and ensuring normal operation of the receiver.<br> 4. Features protection against reversed power polarity. If the power is accidentally reversed, it will not cause damage to the UBEC.<br> Advantages compared to traditional BEC:<br> 5. Compared to linear regulated BEC, the advantages of switch-mode power supply BEC are primarily reflected in the following: When using 3-cell (11.1V) or higher batteries, it significantly reduces BEC heat generation and improves overall efficiency.<br> For example, when using 4 lithium batteries, the operating voltage is approximately 14.8V.<br> With a traditional linear regulator, to output 5V/1A, the power supply must also input 1A.<br> Therefore, there is a power consumption of 14.8V × 1A = 14.8W on the BEC. However, the actual useful output of the BEC is only 5V × 1A = 5W, resulting in an overall efficiency of 5/14.8 = 33.8%. The remaining 9.8W of power consumption is converted into heat, causing the BEC to overheat, the chip to enter protection mode, and the system to malfunction;<br> 6. Using a switching power supply method, to output 5V/1A current, our actual testing shows that the power supply only needs to input 0.38A current, i.e., 14.8V × 0.38A = 5.6W power consumption.<br> UBEC-3A specifications:<br> Operating voltage: Lipo 2S-5S<br> Continuous current: 3A<br> Peak current: MIN 4A for 20 seconds<br> Output voltage: 5.25V ±0.5V<br> Weight: 6g<br> UBEC-5A Specifications:<br> Operating voltage: 5.5V-35V Lipo 2S-8S<br> Continuous current: 5A<br> Peak current: MIN 6A for 20 seconds<br> Output Voltage: 5.25V ±0.5V<br> Weight: 18g<br> UBEC-7A Specifications:<br> Operating Voltage: 5.5V-35V Lipo 2S-8S<br> Continuous Current: 6A<br> Peak Current: MIN 7.5A for 20 seconds<br> Output Voltage: 5.25V ±0.5V<br> Weight: 18g<br> UBEC-15A Specifications:<br> Operating Voltage: 6-12S (23-45V)<br> Continuous Current: 15A<br> Peak Current: 30A/10 seconds<br> Dimensions: 55x28x5mm<br> Weight: 36g<br> Package Includes:<br> 1x Receiver Power Supply<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
